ABSTRACT
INTRODUCTION AND OBJECTIVES: In patients undergoing percutaneous coronary intervention (PCI) in the workup pre-transcatheter aortic valve replacement (TAVR), the clinical impact of coronary revascularization complexity remains unknown. This study sought to examine the impact of PCI complexity on clinical outcomes after TAVR in patients undergoing PCI in the preprocedural workup. METHODS: This was a multicenter study including consecutive patients scheduled for TAVR with concomitant significant coronary artery disease. Complex PCI was defined as having at least 1 of the following features: 3 vessels treated, ≥ 3 stents implanted, ≥ 3 lesions treated, bifurcation with 2 stents implanted, total stent length >60mm, or chronic total occlusion. The rates of major adverse cardiac events (MACE), including cardiovascular mortality, myocardial infarction, and coronary revascularization were evaluated. RESULTS: A total of 1550 patients were included, of which 454 (29.3%) underwent complex PCI in the pre-TAVR workup. After a median follow-up period of 2 [1-3] years after TAVR, the incidence of MACE was 9.6 events per 100 patients-years. Complex PCI significantly increased the risk of cardiac death (HR, 1.44; 95%CI, 1.01-2.07), nonperiprocedural myocardial infarction (HR, 1.52; 95%CI, 1.04-2.21), and coronary revascularization (HR, 2.46; 95%CI, 1.44-4.20). In addition, PCI complexity was identified as an independent predictor of MACE after TAVR (HR, 1.31; 95%CI, 1.01-1.71; P=.042). CONCLUSIONS: In TAVR candidates with significant coronary artery disease requiring percutaneous treatment, complex revascularization was associated with a higher risk of MACE. The degree of procedural complexity should be considered a strong determinant of prognosis in the PCI-TAVR population.
ABSTRACT
To date, the best approach to coronary bifurcation lesion remains unsettled, and the parameters to guide side branch ballooning or stenting are not yet defined. This study aimed to compare the survival outcomes after provisional stenting with versus without side branch intervention. A cohort was conducted on 132 patients who underwent coronary angiography at Toulouse University Hospital for ST-segment elevation myocardial infarction with large culprit nonleft main coronary bifurcation lesion. Study participants were divided into 2 groups depending on the performance or not of a side branch intervention. We observed the living status at 1-year after hospital discharge. Side branch intervention by balloon inflation or final balloon kissing technique was performed in 34.1% of study participants. At 1-year follow-up, the incidence of all-cause mortality was 7.8 per 100 person-years (95% confidence interval [CI] 4.1 to 15), and although it seemed higher in the side branch intervention group (10 per 100 person-years [95% CI 3.8 to 26.7] vs 6.6 per 100 persons-years [95% CI 2.8 to 15.9]), the survival analyses showed no differences in survival outcomes (hazard ratio side branch intervention 1.55 [0.42 to 5.78], p = 0.513). In conclusion, in the setting of a coronary bifurcation causing ST-segment elevation myocardial infarction, simple provisional stenting without side branch intervention showed a low mortality rate and no differences in the 1-year survival outcomes.

Paravalvular leak (PVL), conduction disturbances, and vascular complications remain the most common complications after TAVR. To address these adverse outcomes, the third generation of transcatheter heart valves has been developed. The last generation prosthesis provides an outer pericardial wrap for enhanced sealing and PVL prevention. This study aimed to compare the incidence and severity of PVL and 1-year survival after TAVR using SAPIEN 3 with those using EVOLUT PRO. An observational retrospective analysis was conducted in 1,481 patients who underwent TAVR for symptomatic severe aortic stenosis in 6 different European centers. The primary end point was to assess the frequency and severity of PVL at 30 days after TAVR. The secondary end point was to compare 1-year survival using EVOLUT PRO with that using SAPIEN 3. SAPIEN 3 transcatheter heart valve was implanted in 78.3% of study participants (n = 1,160) whereas EVOLUT PRO was implanted in 21.7% (n = 321). PVL is more commonly observed in patients treated with EVOLUT PRO at prehospital discharge (55.1% vs 37.3%) and at 1-month (51% vs 41.4%) and 1-year (51.3% vs 39.3%) follow-up. This difference mainly concerns low-grade (mild/trace) PVL. The frequency of high-degree (moderate/severe) PVL was almost similar in both groups throughout the study period (5.3% vs 5.8% before hospital discharge, 4% vs 3.1% at 1 month, and 3.2% vs 4.9% at 1 year). No significant difference in survival over 1 year has been observed (hazard ratio 0.73 [0.33 to 1.63], p = 0.442) (Graphical abstract). In conclusion, the detection rate of PVL after TAVR with third-generation heart valves remains high, and there are no major differences between the devices regarding the frequency of significant (moderate/severe) PVL and survival.

BACKGROUND: In patients undergoing percutaneous coronary intervention (PCI) in the work-up pre-transcatheter aortic valve replacement (TAVR), the incidence and clinical impact of late bleeding events (LBEs) remain largely unknown. OBJECTIVES: This study sought to determine the incidence, clinical characteristics, associated factors, and outcomes of LBEs in patients undergoing PCI in the work-up pre-TAVR. METHODS: This was a multicenter study including 1,457 consecutive patients (mean age 81 ± 7 years; 41.5% women) who underwent TAVR and survived beyond 30 days. LBEs (>30 days post-TAVR) were defined according to the Valve Academic Research Consortium-2 criteria. RESULTS: LBEs occurred in 116 (7.9%) patients after a median follow-up of 23 (IQR: 12-40) months. Late bleeding was minor, major, and life-threatening or disabling in 21 (18.1%), 63 (54.3%), and 32 (27.6%) patients, respectively. Periprocedural (<30 days post-TAVR) major bleeding and the combination of antiplatelet and anticoagulation therapy at discharge were independent factors associated with LBEs (P ≤ 0.02 for all). LBEs conveyed an increased mortality risk at 4-year follow-up compared with no bleeding (43.9% vs 36.0; P = 0.034). Also, LBE was identified as an independent predictor of all-cause mortality after TAVR (HR: 1.39; 95% CI: 1.05-1.83; P = 0.020). CONCLUSIONS: In TAVR candidates with concomitant significant coronary artery disease requiring percutaneous treatment, LBEs after TAVR were frequent and associated with increased mortality. Combining antiplatelet and anticoagulation regimens and the occurrence of periprocedural bleeding determined an increased risk of LBEs. Preventive strategies should be pursued for preventing late bleeding after TAVR, and further studies are needed to provide more solid evidence on the most safe and effective antithrombotic regimen post-TAVR in this challenging group of patients.

BACKGROUND: The burden of cardiac death after transcatheter aortic valve replacement (TAVR), particularly from advanced heart failure (HF) and sudden cardiac death (SCD), remains largely unknown. OBJECTIVES: This study sought to evaluate the incidence and predictors of SCD and HF-related death in TAVR recipients treated with newer-generation devices. METHODS: This study included a total of 5,421 consecutive patients who underwent TAVR with newer-generation devices using balloon (75.7%) or self-expandable (24.3%) valves. RESULTS: After a median follow-up of 2 (IQR: 1-3) years, 976 (18.0%) patients had died, 50.8% from cardiovascular causes. Advanced HF and SCD accounted for 11.6% and 7.5% of deaths, respectively. Independent predictors of HF-related death were atrial fibrillation (HR: 2.17; 95% CI: 1.47-3.22; P < 0.001), prior pacemaker (HR: 1.79; 95% CI: 1.10-2.92; P = 0.01), reduced left ventricular ejection fraction (HR: 1.08 per 5% decrease; 95% CI: 1.01-1.14; P = 0.02), transthoracic approach (HR: 2.50; 95% CI: 1.37-4.55; P = 0.003), and new-onset persistent left bundle branch block (HR: 1.85; 95% CI: 1.14-3.02; P = 0.01). Two baseline characteristics (diabetes, HR: 1.81; 95% CI: 1.13-2.89; P = 0.01; and chronic kidney disease, HR: 1.72; 95% CI: 1.02-2.90; P = 0.04) and 3 procedural findings (valve in valve, HR: 2.17; 95% CI: 1.01-4.64; P = 0.04; transarterial nontransfemoral approach, HR: 2.23; 95% CI: 1.23-4.48; P = 0.01; and periprocedural ventricular arrhythmia, HR: 7.19; 95% CI: 2.61-19.76; P < 0.001) were associated with an increased risk of SCD after TAVR. CONCLUSIONS: Advanced HF and SCD accounted for a fifth of deaths after TAVR in contemporary practice. Potentially treatable factors leading to increased risk of HF deaths and SCD were identified, such as arrhythmia/dyssynchrony factors for HF and valve-in-valve TAVR or periprocedural ventricular arrhythmias for SCD.

Background: In recent years, the number of patients with failed surgically implanted aortic bioprostheses and the number of candidates for valve-in-valve transcatheter aortic valve replacement (VIV-TAVR) have been increasing. Objectives: The purpose of this study is to evaluate the efficacy, safety, and long-term survival outcomes of VIV-TAVR compared with the benchmark native valve transcatheter aortic valve replacement (NV-TAVR). Methods: A cohort study was conducted on patients who underwent TAVR in the department of cardiology at Toulouse University Hospital, Rangueil, France between January 2016 and January 2020. The study population was divided into two groups: NV-TAVR (N = 1589) and VIV-TAVR (N = 69). Baseline characteristics, procedural data, in-hospital outcomes, and long-term survival outcomes were observed. Results: In comparison with NV-TAVR, there are no differences in TAVR success rate (98.6 vs. 98.8%, p = 1), per-TAVR complications (p = 0.473), and length of hospital stay (7.5 ± 50.7 vs. 4.4 ± 2.8, p = 0.612). The prevalence of in-hospital adverse outcomes did not differ among study groups, including acute heart failure (1.4 vs. 1.1%), acute kidney injury (2.6, 1.4%), stroke (0 vs. 1.8%, p = 0.630), vascular complications (p = 0.307), bleeding events (0.617), and death (1.4 vs. 2.6%). VIV-TAVR was associated with a higher residual aortic gradient [OR = 1.139, 95%CI (1.097-1.182), p = 0.001] and a lower requirement for permanent pacemaker implantation [OR = 0.235 95%CI (0.056-0.990), p = 0.048]. Over a mean follow-up period of 3.44 ± 1.67 years, no significant difference in survival outcomes has been observed (p = 0.074). Conclusion: VIV-TAVR shares the safety and efficacy profile of NV-TAVR. It also represents a better early outcome but a higher non-significant long-term mortality rate.
ABSTRACT
BACKGROUND: Transcatheter aortic valve implantation now has a major role in the treatment of patients with severe aortic stenosis. However, evidence is scarce on its feasibility and safety to treat patients with pure aortic regurgitation. AIMS: We sought to evaluate the results of transcatheter aortic valve implantation using the balloon-expandable SAPIEN 3 transcatheter heart valve (Edwards Lifesciences, Irvine, CA, USA) in patients with pure aortic regurgitation on native non-calcified valves. METHODS: We conducted a retrospective and prospective French multicentre observational study. We included all patients with symptomatic severe pure aortic regurgitation on native non-calcified valves, contraindicated to or at high risk for surgical valve replacement, who underwent transcatheter aortic valve implantation using the SAPIEN 3 transcatheter heart valve. RESULTS: A total of 37 patients (male sex, 73%) with a median age of 81years (interquartile range 69-85years) were screened using transthoracic echocardiography and computed tomography and were included at eight French centres. At baseline, 83.8% of patients (n=31) had dyspnoea New York Heart Association class≥III. The device success rate was 94.6% (n=35). At 30days, the all-cause mortality rate was 8.1% (n=3) and valve migration occurred in 10.8% of cases (n=4). Dyspnoea New York Heart Association class≤II was seen in 86.5% of patients (n=32), and all survivors had aortic regurgitation grade≤1. At 1-year follow-up, all-cause mortality was 16.2% (n=6), 89.7% (n=26/29) of survivors were in New York Heart Association class≤II and all had aortic regurgitation grade≤2. CONCLUSION: Transcatheter aortic valve implantation using the SAPIEN 3 transcatheter heart valve seems promising to treat selected high-risk patients with pure aortic regurgitation on non-calcified native valves, contraindicated to surgical aortic valve replacement.

BACKGROUND: Echocardiography is the primary imaging modality for diagnosis of infective endocarditis (IE) in prosthetic valve endocarditis (PVE) including IE after transcatheter aortic valve implantation (TAVI). This study aimed to evaluate the characteristics and clinical outcomes of patients with absent compared with evident echocardiographic signs of TAVI-IE. METHODS: Patients with definite TAVI-IE derived from the Infectious Endocarditis after TAVI International Registry were investigated comparing those with absent and evident echocardiographic signs of IE defined as vegetation, abscess, pseudo-aneurysm, intracardiac fistula, or valvular perforation or aneurysm. RESULTS: Among 578 patients, 87 (15.1%) and 491 (84.9%) had absent (IE-neg) and evident (IE-pos) echocardiographic signs of IE, respectively. IE-neg were more often treated via a transfemoral access with a self-expanding device and had higher rates of peri-interventional complications (eg, stroke, major vascular complications) during the TAVI procedure (P < .05 for all). IE-neg had higher rates of IE caused by Staphylococcus aureus (33.7% vs 23.2%; P = .038) and enterococci (37.2% vs 23.8%; P = .009) but lower rates of coagulase-negative staphylococci (4.7% vs 20.0%, P = .001). IE-neg was associated with the same dismal prognosis for in-hospital mortality in a multivariate binary regression analysis (odds ratio: 1.51; 95% confidence interval [CI]: .55-4.12) as well as a for 1-year mortality in Cox regression analysis (hazard ratio: 1.10; 95% CI: .67-1.80). CONCLUSIONS: Even with negative echocardiographic imaging, patients who have undergone TAVI and presenting with positive blood cultures and symptoms of infection are a high-risk patient group having a reasonable suspicion of IE and the need for an early treatment initiation.

Background: The link between dental, infective and obstructive cardiovascular diseases is debatable. Aim: To systematically review the literature to assess the association between dental conditions and development of cardiovascular disease. Methods: The systematic review was conducted following the PRISMA guidelines using PubMed (Medline), Web of Science, Scopus, EMBASE and SciELO. Results: Out of 6680 records, 82 articles were eligible for inclusion after reviewing titles and abstracts. No association between dental disease and cardiovascular disease has been observed in 10 studies while a potential link has been suggested by the remaining trials. Tooth loss and periodontitis are the main evaluated oral conditions while coronary artery disease, stroke, atherosclerosis and myocardial infarction represent the major cardiovascular events. The interaction between these two clinical entities is based on direct mechanism mediated by systemic inflammatory response, leakage of cytokines and endothelial cells invasion by oral pathogens and indirect mechanism mediated by common risk factors or confounders. Conclusions: It seems that tooth loss, periodontitis and poor oral hygiene increase the risk of atherosclerotic cardiovascular events, and subsequently oral health care professionals could contribute to public health cardiovascular control efforts.
ABSTRACT
BACKGROUND: Outcomes after transcatheter aortic valve replacement (TAVR) and infectious diseases may vary according to sex. METHODS: This multicentre study aimed to determine the sex differences in clinical characteristics, management, and outcomes of infective endocarditis (IE) after TAVR. A total of 579 patients (217 women, 37.5%) who had the diagnosis of definite IE following TAVR were included retrospectively from the Infectious Endocarditis After TAVR International Registry. RESULTS: Women were older (80 ± 8 vs 78 ± 8 years; P = 0.001) and exhibited a lower comorbidity burden. Clinical characteristics and microbiological profiles were similar between men and women, but culture-negative IE was more frequent in women (9.9% vs 4.3%; P = 0.009). A high proportion of patients had a clinical indication for surgery (54.4% in both groups; P = 0.99), but a surgical intervention was performed in a minority of patients (women 15.2%, men 20.3%; P = 0.13). The mortality rate at index IE hospitalisation was similar in both groups (women 35.4%, men 31.7%; P = 0.37), but women exhibited a higher mortality rate at 2-year follow-up (63% vs 52.1%; P = 0.021). Female sex remained an independent risk factor for cumulative mortality in the multivariable analysis (adjusted HR 1.28, 95% CI 1.02-1.62; P = 0.035). After adjustment for in-hospital events, surgery was not associated with better outcomes in women. CONCLUSIONS: There were no significant sex-related differences in the clinical characteristics and management of IE after TAVR. However, female sex was associated with increased 2-year mortality risk.

BACKGROUND: Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a common disorder characterized by the presence of clinical criteria for acute myocardial infarction in the absence of obstructive coronary artery disease on angiography. We aim to investigate the relationship between myocardial bridging (MB) and MINOCA. METHODS AND RESULTS: An observational retrospective study was conducted on 15 036 patients who had been referred for coronary angiography and who fulfilled the Fourth Universal Definition of Myocardial Infarction. The study population was divided into ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) patients, from which we defined two main groups: the MINOCA group and the coronary artery disease (CAD) group. Statistical analyses were carried out by using SPSS, version 20. The prevalence of angiographic MB among the groups was significantly greater in the MINOCA group (2.9% vs. 0.8%). MINOCA accounted for 14.5% of spontaneous myocardial infarction, and the clinical presentation was more frequently NSTEMI rather than STEMI (84.3% vs. 15.7%). After adjusting for confounders, multivariate analyses showed a positive association between MB and MINOCA [odds ratio = 3.28, 95% CI (2.34; 4.61) P < 0.001]. Cardiovascular risk factors were less common in the MINOCA population, which was younger and more often female. CONCLUSION: MB is a risk factor for MINOCA. Because MB prevalence differed significantly between the controls (CAD group) and cases (MINOCA group), which were positively associated to MB, it seems likely that MB would be a potential cause of MINOCA. Investigations for MB in MINOCA cases and especially in NSTEMI patients seem necessary.

Scarce data exist on mitral valve (MV) infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). This multicenter study included a total of 579 patients with a diagnosis of definite IE after TAVI from the IE after TAVI International Registry and aimed to evaluate the incidence, characteristics, management, and outcomes of MV-IE after TAVI. A total of 86 patients (14.9%) had MV-IE. These patients were compared with 284 patients (49.1%) with involvement of the transcatheter heart valve (THV) only. Two factors were found to be associated with MV-IE: the use of self-expanding valves (adjusted odds ratio 2.49, 95% confidence interval [CI] 1.23 to 5.07, p = 0.012), and the presence of an aortic regurgitation ≥2 at discharge (adjusted odds ratio 3.33; 95% CI 1.43 to 7.73, p <0.01). There were no differences in IE timing and causative microorganisms between groups, but surgical management was significantly lower in patients with MV-IE (6.0%, vs 21.6% in patients with THV-IE, p = 0.001). All-cause mortality rates at 2-year follow-up were high and similar between patients with MV-IE (51.4%, 95% CI 39.8 to 64.1) and patients with THV-IE (51.5%, 95% CI 45.4 to 58.0) (log-rank p = 0.295). The factors independently associated with increased mortality risk in patients with MV-IE were the occurrence of heart failure (adjusted p <0.001) and septic shock (adjusted p <0.01) during the index hospitalization. One of 6 IE episodes after TAVI is localized on the MV. The implantation of a self-expanding THV and the presence of an aortic regurgitation ≥2 at discharge were associated with MV-IE. Patients with MV-IE were rarely operated on and had a poor prognosis at 2-year follow-up.

BACKGROUND: Morbidly obese (MO) patients are increasingly undergoing transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) for severe aortic stenosis (AS). However, the best therapeutic strategy for these patients remains a matter for debate. AIMS: Our aim was to compare the periprocedural and mid-term outcomes in MO patients undergoing TAVR versus SAVR. METHODS: A multicentre retrospective study including consecutive MO patients (body mass index ≥40 kg/m2, or ≥35 kg/m2 with obesity-related comorbidities) from 18 centres undergoing either TAVR (n=860) or biological SAVR (n=696) for severe AS was performed. Propensity score matching resulted in 362 pairs. RESULTS: After matching, periprocedural complications, including blood transfusion (14.1% versus 48.1%; p<0.001), stage 2-3 acute kidney injury (3.99% versus 10.1%; p=0.002), hospital-acquired pneumonia (1.7% versus 5.8%; p=0.005) and access site infection (1.5% versus 5.5%; p=0.013), were more common in the SAVR group, as was moderate to severe patient-prosthesis mismatch (PPM; 9.9% versus 39.4%; p<0.001). TAVR patients more frequently required permanent pacemaker implantation (14.4% versus 5.6%; p<0.001) and had higher rates of ≥moderate residual aortic regurgitation (3.3% versus 0%; p=0.001). SAVR was an independent predictor of moderate to severe PPM (hazard ratio [HR] 1.80, 95% confidence interval [CI]: 1.25-2.59; p=0.002), while TAVR was not. In-hospital mortality was not different between groups (3.9% for TAVR versus 6.1% for SAVR; p=0.171). Two-year outcomes (including all-cause and cardiovascular mortality, and readmissions) were similar in both groups (log-rank p>0.05 for all comparisons). Predictors of all-cause 2-year mortality differed between the groups; moderate to severe PPM was a predictor following SAVR (HR 1.78, 95% CI: 1.10-2.88; p=0.018) but not following TAVR (p=0.737). CONCLUSIONS: SAVR and TAVR offer similar mid-term outcomes in MO patients with severe AS, however, TAVR offers some advantages in terms of periprocedural morbidity.

BACKGROUND: Scarce data exist about early infective endocarditis (IE) after trans-catheter aortic valve replacement (TAVR). OBJECTIVE: The objective was to evaluate the characteristics, management, and outcomes of very early (VE) IE (≤ 30 days) after TAVR. METHODS: This multicenter study included a total of 579 patients from the Infectious Endocarditis after TAVR International Registry who had the diagnosis of definite IE following TAVR. RESULTS: Ninety-one patients (15.7%) had VE-IE. Factors associated with VE-IE (vs. delayed IE (D-IE)) were female gender (p = 0.047), the use of self-expanding valves (p < 0.001), stroke (p = 0.019), and sepsis (p < 0.001) after TAVR. Staphylococcus aureus was the main pathogen among VE-IE patients (35.2% vs. 22.7% in the D-IE group, p = 0.012), and 31.2% of Staphylococcus aureus infections in the VE-IE group were methicillin-resistant (vs. 14.3% in the D-IE group, p = 0.001). The second-most common germ was enterococci (34.1% vs. 24.4% in D-IE cases, p = 0.05). VE-IE was associated with very high in-hospital (44%) and 1-year (54%) mortality rates. Acute renal failure following TAVR (p = 0.001) and the presence of a non-enterococci pathogen (p < 0.001) were associated with an increased risk of death. CONCLUSION: A significant proportion of IE episodes following TAVR occurs within a few weeks following the procedure and are associated with dismal outcomes. Some baseline and TAVR procedural factors were associated with VE-IE, and Staphylococcus aureus and enterococci were the main causative pathogens. These results may help to select the more appropriate antibiotic prophylaxis in TAVR procedures and guide the initial antibiotic therapy in those cases with a clinical suspicion of IE. Very early infective endocarditis after trans-catheter aortic valve replacement. VE-IE indicates very early infective endocarditis (≤30 days post TAVR). D-IE indicates delayed infective endocarditis.

BACKGROUND: The optimal treatment of patients developing infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI) is uncertain. OBJECTIVES: The goal of this study was to investigate the clinical characteristics and outcomes of patients with TAVI-IE treated with cardiac surgery and antibiotics (IE-CS) compared with patients treated with antibiotics alone (IE-AB). METHODS: Crude and inverse probability of treatment weighting analyses were applied for the treatment effect of cardiac surgery vs medical therapy on 1-year all-cause mortality in patients with definite TAVI-IE. The study used data from the Infectious Endocarditis after TAVI International Registry. RESULTS: Among 584 patients, 111 patients (19%) were treated with IE-CS and 473 patients (81%) with IE-AB. Compared with IE-AB, IE-CS was not associated with a lower in-hospital mortality (HRunadj: 0.85; 95% CI: 0.58-1.25) and 1-year all-cause mortality (HRunadj: 0.88; 95% CI: 0.64-1.22) in the crude cohort. After adjusting for selection and immortal time bias, IE-CS compared with IE-AB was also not associated with lower mortality rates for in-hospital mortality (HRadj: 0.92; 95% CI: 0.80-1.05) and 1-year all-cause mortality (HRadj: 0.95; 95% CI: 0.84-1.07). Results remained similar when patients with and without TAVI prosthesis involvement were analyzed separately. Predictors for in-hospital and 1-year all-cause mortality included logistic EuroSCORE I, Staphylococcus aureus, acute renal failure, persistent bacteremia, and septic shock. CONCLUSIONS: In this registry, the majority of patients with TAVI-IE were treated with antibiotics alone. Cardiac surgery was not associated with an improved all-cause in-hospital or 1-year mortality. The high mortality of patients with TAVI-IE was strongly linked to patients' characteristics, pathogen, and IE-related complications.

OBJECTIVES: Obesity may increase the risk of vascular complications in transfemoral (TF) transcatheter aortic valve replacement (TAVR) procedures. The transcarotid (TC) approach has recently emerged as an alternative access in TAVR. We sought to compare vascular complications and early clinical outcomes in obese patients undergoing TAVR either by TF or TC vascular access. METHODS: Multicentre registry including obese patients undergoing TF- or TC-TAVR in 15 tertiary centres. All patients received newer-generation transcatheter heart valves. For patients exhibiting unfavourable ileo-femoral anatomic characteristics, the TC approach was favoured in 3 centres with experience with it. A propensity score analysis was performed for overcoming unbalanced baseline covariates. The primary end point was the occurrence of in-hospital vascular complications (Valve Academic Research Consortium-2 criteria). RESULTS: A total of 539 patients were included, 454 (84.2%) and 85 (15.8%) had a TF and TC access, respectively. In the propensity-adjusted cohort (TF: 442 patients; TC: 85 patients), both baseline and procedural valve-related characteristics were well-balanced between groups. A significant decrease in vascular complications was observed in the TC group (3.5% vs 12% in the TF group, odds ratio: 0.26, 95% CI: 0.07-0.95, P = 0.037). There were no statistically significant differences between groups regarding in-hospital mortality (TC: 2.8%, TF: 1.5%), stroke (TC: 1.2%, TF: 0.4%) and life-threatening/major bleeding events (TC: 2.8%, TF: 3.8%). CONCLUSIONS: In patients with obesity undergoing TAVR with newer-generation devices, the TC access was associated with a lower rate of vascular complications. Larger randomized studies are warranted to further assess the better approach for TAVR in obese patients.

BACKGROUND: Infective endocarditis (IE) following transcatheter aortic valve replacement (TAVR) has been associated with a dismal prognosis. However, scarce data exist on IE perivalvular extension (PEE) in such patients. METHODS: This multicenter study included 579 patients who had the diagnosis of definite IE at a median of 171 (53-421) days following TAVR. PEE was defined as the presence of an intracardiac abscess, pseudoaneurysm, or fistula. RESULTS: A total of 105 patients (18.1%) were diagnosed with PEE (perivalvular abscess, pseudoaneurysm, fistula, or a combination in 87, 7, 7, and 4 patients, respectively). A history of chronic kidney disease (adjusted odds ratio [ORadj], 2.08; 95% confidence interval [CI]: 1.27-3.41; Pâ =â .003) and IE secondary to coagulase-negative staphylococci (ORadj, 2.71; 95% CI: 1.57-4.69; Pâ <â .001) were associated with an increased risk of PEE. Surgery was performed at index IE episode in 34 patients (32.4%) with PEE (vs 15.2% in patients without PEE, Pâ <â .001). In-hospital and 2-year mortality rates among PEE-IE patients were 36.5% and 69.4%, respectively. Factors independently associated with an increased mortality were the occurrence of other complications (stroke post-TAVR, acute renal failure, septic shock) and the lack of surgery at index IE hospitalization (padjâ <â 0.05 for all). CONCLUSIONS: PEE occurred in about one-fifth of IE post-TAVR patients, with the presence of coagulase-negative staphylococci and chronic kidney disease determining an increased risk. Patients with PEE-IE exhibited high early and late mortality rates, and surgery during IE hospitalization seemed to be associated with better outcomes.

BACKGROUND: Staphylococcus aureus (SA) has been extensively studied as causative microorganism of surgical prosthetic-valve infective endocarditis (IE). However, scarce evidence exists on SA IE after transcatheter aortic valve replacement (TAVR). METHODS: Data were obtained from the Infectious Endocarditis After TAVR International Registry, including patients with definite IE after TAVR from 59 centres in 11 countries. Patients were divided into 2 groups according to microbiologic etiology: non-SA IE vs SA IE. RESULTS: SA IE was identified in 141 patients out of 573 (24.6%), methicillin-sensitive SA in most cases (115/141, 81.6%). Self-expanding valves were more common than balloon-expandable valves in patients presenting with early SA IE. Major bleeding and sepsis complicating TAVR, neurologic symptoms or systemic embolism at admission, and IE with cardiac device involvement (other than the TAVR prosthesis) were associated with SA IE (P < 0.05 for all). Among patients with IE after TAVR, the likelihood of SA IE increased from 19% in the absence of those risk factors to 84.6% if ≥ 3 risk factors were present. In-hospital (47.8% vs 26.9%; P < 0.001) and 2-year (71.5% vs 49.6%; P < 0.001) mortality rates were higher among patients with SA IE vs non-SA IE. Surgery at the time of index SA IE episode was associated with lower mortality at follow-up compared with medical therapy alone (adjusted hazard ratio 0.46, 95% CI 0.22-0.96; P = 0.038). CONCLUSIONS: SA IE represented approximately 25% of IE cases after TAVR and was associated with very high in-hospital and late mortality. The presence of some features determined a higher likelihood of SA IE and could help to orientate early antibiotic regimen selection. Surgery at index SA IE was associated with improved outcomes, and its role should be evaluated in future studies.

Introduction: Up to date, the management of coronary artery aneurysm (CAA) is not well defined and depends on local heart team decision. Data reported in literature are scarce and controversial. We aim to compare the long-term outcomes of different therapeutic strategies of CAA (medical vs percutaneous coronary intervention (PCI) vs coronary artery bypass graft(CABG)). Materials and Methods: A retrospective cohort study was conducted on 100 consecutive patients who underwent coronary angiography at Toulouse University Hospital, Toulouse France and fulfilled the diagnostic criteria of CAA. Coronary angiograms were reviewed, and all necessary data were collected. CAA was defined by a coronary dilation exceedingly at least 50% of reference coronary diameter. Results: We identified 100 patients with CAA with a mean age of 67.9 ± 12 years. The left anterior descending coronary artery was most affected (36%). CAA is associated with significant coronary artery disease in 78% of cases. The incidence of major adverse cardiovascular and cerebrovascular events (MACCE) was 13% during a median follow-up period of 46.2 ± 24 months. A 53% of patients underwent PCI or CABG. The rate of MACCE was lower in CABG group (9.1%) compared to PCI (14.3%) and medical (12.8%) groups, but without reaching statistically significant level. Longitudinal aneurysm diameter was positively linked to MACCE [OR = 1.109, 95% CI (1.014-1.214), p = 0.024]. No benefits have been attributed to anticoagulant regimen over antiplatelet therapy. Conclusions: In our retrospective observational study, there seems to be no significant differences in MACCE-free survival between all groups (Medical vs PCI vs CABG). Larger longitudinal aneurysm diameter was identified as a predictor of poor prognosis during follow-up.
ABSTRACT
BACKGROUND: Procedural improvements combined with the contemporary clinical profile of patients undergoing transcatheter aortic valve replacement (TAVR) may have influenced the incidence and outcomes of infective endocarditis (IE) following TAVR. We aimed to determine the temporal trends, characteristics, and outcomes of IE post-TAVR. METHODS: Observational study including 552 patients presenting definite IE post-TAVR. Patients were divided in 2 groups according to the timing of TAVR (historical cohort [HC]: before 2014; contemporary cohort [CC]: after 2014). RESULTS: Overall incidence rates of IE were similar in both cohorts (CC vs HC: 5.45 vs 6.52 per 1000 person-years; P = .12), but the rate of early IE was lower in the CC (2.29 vs 4.89, P < .001). Enterococci were the most frequent microorganism. Most patients presented complicated IE (CC: 67.7%; HC: 69.6%; P = .66), but the rate of surgical treatment remained low (CC: 20.7%; HC: 17.3%; P = .32). The CC exhibited lower rates of in-hospital acute kidney injury (35.1% vs 44.6%; P = .036) and in-hospital (26.6% vs 36.4%; P = .016) and 1-year (37.8% vs 53.5%; P < .001) mortality. Higher logistic EuroScore, Staphylococcus aureus etiology, and complications (stroke, heart failure, and acute renal failure) were associated with in-hospital mortality in multivariable analyses (P < .05 for all). CONCLUSIONS: Although overall IE incidence has remained stable, the incidence of early IE has declined in recent years. The microorganism, high rate of complications, and very low rate of surgical treatment remained similar. In-hospital and 1-year mortality rates were high but progressively decreased over time.
